## Installation
1) Download [latest version](https://cloud.quenon.ru/index.php/s/h98rT9UnaOL4wxR/download?path=%2F&files=unitemp-latest.fap)
2) Copy `unitemp-latest.fap` to `SD card/apps/GPIO` with qFlipper or mobile application
3) Open application on your Flipper: `Applications->GPIO->Temp sensors reader`
Note: If you get the message "API version mismatch" after updating the firmware, download and install Unitemp again
## Need help? Discussions?
